Abracon recommends following a standard PCB layout for oscillators, with a ground plane underneath the device, and keeping the input and output traces as short as possible. A 4-layer PCB with a dedicated ground plane is recommended for high-frequency designs.
To ensure reliable startup, Abracon recommends applying a clean power supply, using a bypass capacitor (e.g., 0.1uF) between VCC and GND, and ensuring the input voltage is within the specified range. Additionally, the oscillator should be powered up slowly (e.g., with a soft-start circuit) to prevent inrush currents.
While the datasheet specifies an operating temperature range of -40°C to +85°C, Abracon recommends derating the oscillator's frequency stability and output amplitude at extreme temperatures. For reliable operation, it's recommended to operate the oscillator within a temperature range of -20°C to +70°C.
The ASPI-0628-470M-T1 is designed to meet the requirements of MIL-STD-883, Method 2002.4, which includes vibration testing. However, Abracon recommends consulting with their application engineers to ensure the oscillator meets the specific vibration requirements of your application.
To troubleshoot issues, Abracon recommends checking the power supply voltage, ensuring proper PCB layout and routing, and verifying the load capacitance. If issues persist, consult Abracon's application notes and contact their technical support team for assistance.
